Tokyo Station Monkey or Attic Monkey of Tokyo Station Yaesu Exit is a cryptid that has appeared at Tokyo Station, Tokyo, Japan.
Around December 1974 (as of February 1975, he said it happened about two months earlier. The detailed timing is unknown), the manager of a coffee shop in the underground area of the Yaesu Exit of Tokyo Station heard strange animal noises.
On February 10, 1975, a university student was walking in the underground area of Tokyo Station Yaesu Exit when two ceiling panels came off and fell down. At this time, the college student heard strange cries and saw three strange monkey-like creatures hanging from what looked like pipes or beams in the back of the ceiling where the ceiling panels had come off.
The management of Tokyo Station began to investigate the cause of the problem in response to this sighting. They discovered that the cause of the falling ceiling panels was an error made during the work of the plumbing crew working on the project at the time. As for the monkey-like creature, they believed that some debris may have been caught in the pipes or something else in the ceiling, which may have made it look like a creature.
One blog posted that the creature that looked like a monkey was a stray cat and that this attic was used by the cat to move around, but the source of this information is unknown.
